Formatting a drive is enough to prevent confidential data outflow?

Recommended Posts

Recently, i bought a new external hard drive and now it's not working fine. Since last two days, it hangs whenever i try to store data. I tried several methods to make it healthy again but nothing worked for me. Now i finally decide to replace it and before sending it for replacement i formatted the drive to prevent confidential data outflow. Now i wanted to confirm is it safe now ?

Hey @adi and :wp:

 

To be as certain as one can be, you could encrypt the the drive, then format it again. That would ensure any data that may have been recoverable should be sufficiently destroyed.

As I recall, the encryption scrambles any data and thus would require the key to decrypt it and formatting furthers the destruction since you're not intending to decrypt.

That cool.😃  This is something i wasn't aware off. Year back when i was in need of data erasing i downloaded a tool name as bitraser for file and wiped the entire drive.

Agreed with the top posters. Using TPM and a good hardware encryption like McAfee will definetly render your storage media unreadable by anyone without the cypher. Gov-grade 0 bit wiping is icing on the cake.

 

Of course, dunking it in bleach or Ammonia also works.....

 

Best of luck
